To alwhom. it may concern.'

Be -it known that We, ARTHUR C. Mason vand ALFRED T. STURT, citizens of the United States, and residentsof the cit-y ot Flint, county of'Genes-Le,- State oflldichigan, have joint-ly invented certain new and useful Improyeinents which the :tollowino is a specication.

y This invention relatgesto improvements in the constructive features of automobile en tgilies ot a lli-type and has for one et its objects the economical prodnetionof an etilcient power unit, Another object is to provide a t-type of engine', in which the eastings forming oneehalf thereof are dupli- Cates, respectively, of Athose forming the other halt; thatl is to say, the two Cylinder blocks are duplicates and the tvo cylinder heads are also duplicates.' Another object is to provi-de an engine of sucli'design and ported by transversesupporting members secured to the frame or chassis of an automobile as more particularly set forth in our application executed of even date herevy'ith.1

Referring to the drawings which torni, part of this applicationy in Which similar Specification of 'Letters Patent. @attempted AU in Automobile-Engines, of'

' We will irst describe in general the stru@ ture bymeans of which the engine, which is rear oft the cylinder blocks 18 scribe the the subject-matter of the present intention, is preferably secured to ythe chassis.

Brackets 7, 8, 9 and lO are detachably secured to the side channel beams 5 and' of the chassis and each of these brackets is pro- Videdwith an extension lug -ll to form a seat for the supporting members hereinafterv described y The front supporting member '12 is se curely held .in place on the brackets 7 and 8 by suitable U-bolts 1S, and similarly, the rear support-ing member li is secured to the brackets S) and l0 by the lLl-.bolts 15. The supportingmembers l2 and ll preferably inade of tiat sheet metal punching-rs and thus forni-an extremely convenient ii'ieansy of support for anengine ot the type bodying our invention which is formed by securing together duplicate castings, as will be more particularly hereinafter described.y rI he engine is secureddirectly7 to the rear supportingplate by bolts 15 ywhich enter integral lugs 1.6 and 17 lgwrojecting" troni the and 19. An intermediate plate Q0 is secured to the trout er" the engine by bolts 2l which enter integral lugs and Q3 projecting from the `liront of the cylinder blocks 18 and lh A pin 25 passes through the plates l2 and 20 and is secured in place in the engine.q as shown in Figs. 2 and 3,4 in order' toprovide for a pivotal support for the engine at that point. f i

it will thus be seen that the engine is supported on. the chassis `by the plates iii, and l2, the plates Q0 andi@ being eenn nected by the pivot pin 25, and th'e plates lil and l2 being` 'removably secured to the channel beams 5 and G of the chassis..

1We Will nowVV proceed to particularly destructure of engine embodying4 the subject-matter et the .presentinvention. rlhe engine is of the "lt-tipe and is formed by holding together at the longitudinal medial line duplicate castings forming the cylinder blocks 18 and 19, in each of vwhich is provided a pluralityv or cylinders 726 and 27. rlfhe cylinder heads 2S and 29 are likewise duplicates and 'are lsecured' by boltsl` or in` any suitable mannerl to the cylinder castings or blocks 1S andvlf).` A'llie cylinder headsQS and'29 are prose' in rig. i.

exhaust ports for the respective`manitolds are ceredin the front and' rear ends of the cylinder heads-28 and 29,. the lfront ports being cv early and by .dotted linesv inFig. 2. These ports are also indicated; in dotted' lines'at 35 and The pipes y32 and 33 connect the inlet manifolds ofl both cylinder heads with a single carburetor 34' .which serves' for both manifolds.y lt v'will therefore he seen that at each 'end of each-"cylinder head two ports' are located which communicate 4respectively with the water .'acket and exhaust inanifolds. At 4the" ront' lend'oif the cylinder heads 28 and 29 are securedwater jacket a littingsz'?. land '38, and at the rear ends .of

said cylinder'heads are securedexhaust littings wand 40. I y

ln view ot the fact' that the cylinder lieads are duplicates andmay he interchangeably used, it follows that the fittings 37`and 88, 59 and 40' are duplicates, andare so shaped and constructedthat when turned end for end, the opening 41, as shown in Fig. 6, of the fittings 37 and 38 may be made to register with the portsl 35. The fittings are so positioned at the front oi the engine that the opening 41 is ingregister with the water jacket port 35, and the exhaustl manifold port 36 is closed by the extension plate 42, While' at therear as shown in Fig. 7 so that the exhaust port 36 will register withl the opening '41 oi the fitting', and the portion 42 of the fitting forms a closure'ftor the port 35 yin 4the rear of the engine.

By means of the use of the cylindervheads and fittings as above described, it is obvious that duplicate cylinder head castings may be used,on eitherV the right'for left halll of 'the engine.

The cylinder-castings orA blocks 18 and '19 are .likewise so duplicates .and therefore designed and mounted that they too are interchangeable.. 4

While the .castings 1S and 19 are dupli- Cates, the right casting when mounted to form part of theengine is not symmetrical with the left casting when so mounted. This fact will be readily seen -ironf'i tion ot Fig. 1, where the length of the lug 17 of the casting 19 is greater thairthe length of the lug 2?oi` and the length' of the 'le 23er thecasting i9 is the saineas the the lug 16 'and v19 offset, as

necting rods 43 and 44 of oppositev cylindersv shownv at 35 and 36 in Fig. 8,

f are connected in pairs the 'fittings are positioned changeably than an eXaminaf the same casting, y

- Le'aeee .of the casting 18, and similarly, the lugs 17 and 22 of the respective vcastings are. of the samelength.l

The diierence in length of the-lug. 22 and the lug 23 is tween the centers of adjacent cylinders in the oppositely disposedcastings 18 and 19. By having the cylinders of the castings 18 shown'in Fig. 1,"the conto the same crank equal to the longitudinaldistance at the center in the portion brokenv away in Fig. l, which is the distance be-v pins, `as at 45 of the crank shaft 46. 'This structure is 'clearly shown in Figs. 1 and, 5, and of course, it is to be understood that the structure is the same oppositely disposed cylinders. u r

The castingslS and 19 are provided with portions 47 and 48 which form the upper halt of thecrank casing. 53 and-54 and a central bearing 55 are. secured to the portions 47 and 48 forming the upper halt of the crank` case. These bearings support the crank shaft centrally of the` engine. l

The castings 18 and 19 are secured together at the top of the joint by`bolts 49,v .and at the bottom of the joint by 'bolts 5.0,.

as shown invFigs. 34 andl 5. The lower half of the ,crank case 51 `is formed of va sheet metal punching secured to the upper halt of the 'crank case by screwsor bolts 52..

From the Jforegoing description it will be seen that the V-type of engine-embodied in our invention is built up of two half sections, each one of which is made 'from parts identical shape and size. i i

This construction is very a manufacturing standpoint, as'it is more economical lto construct a great quantity'of identical parts which may tomake two` or more sets of special parts tercli'angeably. A V-typ'e engine made in tivo parts is also more easilyhandled in the course of manufacture than one that is cast less viewed'from ever vstand oint.

Our improved engine 1s so designed that all partsare readily accessible to inspection and repair., and is. so supported on the chas-` sis that the entire enginevmay quickly dismantled.

f As many changes could above construction and many apparently .widely tion could be made without departing from the scope thereof, we intend that all matter ontained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and notin ing sense.
